Abstract
1. Способ прямой плавки, включающий подачу (а) металлоносного исходного материала, содержащего оксиды железа и по меньшей мере 3% масс. оксидов титана, (b) твердого углеродистого исходного материала и (с) кислородосодержащего газа в емкость для прямой плавки, содержащую расплавленную ванну железа и шлака, и прямую плавку металлоносного исходного материала в этой емкости и получение выходных потоков расплавленного железа, расплавленного шлака, содержащего оксиды титана, и отходящего газа, причем способ отличается регулированием условий процесса, как описано здесь, так, что расплавленный шлак имеет вязкость в диапазоне 0,5-5 Пуаз, когда температура шлака в расплавленной ванне в емкости для прямой плавки составляет в диапазоне 1400-1550°С.2. Способ по п.1, при этом расплавленный шлак представляет собой суспензию твердого материала и жидкой фазы, и этот твердый материал представляет собой твердую оксидную фазу при температуре шлака в процессе, в силу чего шлак представляет собой суспензию твердой оксидной фазы в жидкой шлаковой фазе.3. Способ по п.2, включающий регулирование условий процесса регулированием состава шлака и температуры расплавленной ванны таким образом, чтобы она была ниже температуры ликвидуса шлака, так что твердая оксидная фаза выделяется из жидкой фазы, тем самым регулируя вязкость шлака.4. Способ по п.2, включающий регулирование условий процесса так, что твердый материал в расплавленном шлаке составляет по меньшей мере 5% расплавленного шлака.5. Способ по п.4, включающий регулирование условий процесса так, что твердый материал в расплавленном шлаке составляет по меньшей мере 10% расплавленного шлака.6. Спо1. The direct smelting method, comprising supplying (a) a metalliferous starting material containing iron oxides and at least 3% of the mass. titanium oxides, (b) a solid carbonaceous starting material, and (c) an oxygen-containing gas into a direct smelting vessel containing a molten bath of iron and slag, and direct melting of the metal-bearing starting material in this vessel and obtaining output streams of molten iron, molten slag containing oxides titanium, and off-gas, the method being different in controlling the process conditions as described herein, so that the molten slag has a viscosity in the range of 0.5-5 Poise when the temperature of the slag in the molten bath e in the tank for direct melting is in the range of 1400-1550 ° C. 2. The method according to claim 1, wherein the molten slag is a suspension of a solid material and a liquid phase, and this solid material is a solid oxide phase at a temperature of the slag in the process, whereby the slag is a suspension of a solid oxide phase in a liquid slag phase. . The method according to claim 2, including controlling the process conditions by adjusting the composition of the slag and the temperature of the molten bath so that it is lower than the liquidus temperature of the slag, so that the solid oxide phase is separated from the liquid phase, thereby adjusting the viscosity of the slag. The method according to claim 2, comprising controlling the process conditions so that the solid material in the molten slag comprises at least 5% of the molten slag. The method according to claim 4, comprising controlling the process conditions such that the solid material in the molten slag comprises at least 10% of the molten slag. Spo
